How to make a custom first person hand model

[Jetug]

I want to make a custom first person hand model. Can anyone tell me how can I do this or give me examples of open source mods that have done this

I would look at PlayerRenderer#renderHand to see how a hand is rendered normally. Then it's just creating the java model and replacing it via RenderArmEvent and canceling it. If you also want to replace the rendering of whatever is in the hand as well, use RenderHandEvent instead.

I wrote this code and my hand model renders but doesn't follow camera rotation(https://imgur.com/1pgyxUl). I took the PoseStack installation code from GameRenderer#renderLeve.

   @OnlyIn(Dist.CLIENT)
    @SubscribeEvent()
    public static void onRenderHand(RenderArmEvent event)
    {
        if(handRenderer == null)
            handRenderer = new CustomHandRenderer();

        var minecraft = Minecraft.getInstance();
        var camera = minecraft.gameRenderer.getMainCamera();
        var poseStack = new PoseStack();

        poseStack.mulPose(Vector3f.XP.rotationDegrees(camera.getXRot()));
        poseStack.mulPose(Vector3f.YP.rotationDegrees(camera.getYRot() + 180.0F));
        applyItemArmTransform(poseStack, HumanoidArm.RIGHT, 1);

        handRenderer.render(
                null,
                poseStack,
                event.getMultiBufferSource(),
                event.getPackedLight());
        event.setCanceled(true);
    }

For rendering I use GeckoLib

Turns out it was much easier 

    @OnlyIn(Dist.CLIENT)
    @SubscribeEvent()
    public static void onRenderHand(RenderArmEvent event)
    {
        if(handRenderer == null)
            handRenderer = new CustomHandRenderer();

        var poseStack = new PoseStack();
        poseStack.translate(0.5, -0.5, -0.6);

        handRenderer.render(
                null,
                poseStack,
                event.getMultiBufferSource(),
                event.getPackedLight());
        event.setCanceled(true);
    }
